(Bowmanville, Ontario March 31, 2021) The installation and commissioning of a new wet scrubber at St Marys Cement plant in Bowmanville will result in a significant decrease in emissions.

This is the first wet scrubber installed at a cement plant in Canada. The water injection technology washes out and scrubs pollutants from the outlet airstream of the plant. St Marys Cement Plant Operations Manager Jim Storey, stated, “This $25 million investment in technology to improve the plant’s environmental performance has proven to be effective in removing sulphur dioxide (SO2) produced in the cement manufacturing process.  We are also pleased that the scrubber was assembled on-site and installed by local Ontario contractors and crews during our annual scheduled plant shutdown.”
